Etching

Etching

Details

Vapor Etching is another type of dry etch process. In vapor etching the reactive gas that is chosen will spontaneously reacts with a material in the vapor phase without needing to generate a plasma. An example of "Vapor Etching" is the etching of Si using XeF2 gas. Vapor etching is a very simple technique which like wet chemical etching has very good selectivity between different materials. This process is extremely isotropic in nature and is usually used in specific processed where one wants to release a device from the original substrate.
